3.1 Impact moving body Install the anvil of the accelerometer. 3.2 Differential grating laser interferometry When a single frequency of laser light is incident on the moving diffraction grating plane, the diffracted light of different orders is produced differently. Puls frequency shift, taking any two-order diffracted light as the measuring beam to interfere, the frequency of the differential signal and the motion of the grating Speed is a simple linear relationship. The method of measuring the velocity of an object using this scheme is called differential grating laser drying. Involved in the law.

4 Overview

Impact accelerometers are widely used in the measurement of impact. Commonly used impact accelerometers are piezoelectric or piezoresistive. Number The learning model can be simplified to a single degree of freedom second-order system. Mx′′ cx′ kx=f(x) Where. m, c, k --- equivalent detection quality, damping, stiffness; x′′,x′,x—the acceleration, velocity, and displacement acting on the equivalent mass; f(x)---external force.
